All true except it being expensive though. I'm yet to find a major and reliable cloud service provider who can beat AWS on pricing. In fact, most either use or resell AWS under the hood themselves, even Vercel does as it turned out recently; and they're supposed to be one of the most competitive in the industry.
There are some rare exceptions who have their own large scale infrastructure and don't depend on AWS like Hetzner in EU, Alibaba Cloud in China or Ananta Cloud in India, but this market is still emerging.
